Abstract
An open top tub or container is supported for vibration and is adapted to receive a workload of treating media and parts to be treated. The container is vibrated by variable power operated means and includes an end wall having an outlet for removing the workload from the container. The outlet is closed by a door member which is pivotally supported for movement between a closed position and a retracted open position in response to operation of a reversible electric motor. The motor drives a positive drive mechanism which includes a gear reducer connected to an elongated screw which extends through a rotatable nut member connected to the door member. Preferably, the drive mechanism has a high mechanical advantage, and the motor may consist of a DC motor which has a permanently magnetized stator and which is adapted to be continuously energized so that a continuously applied force holds the door member closed while the container and work load are vibrating. A water-tight seal is formed around the door by a resilient seal which contacts an outwardly projecting annular bead.
